# GroupCall

`public class GroupCall`
`extends Object` `implements AutoCloseable`

java.lang.Object
↳ | android.telephony.mbms.GroupCall

Class used to represent a single MBMS group call. After a call has been started with `MbmsGroupCallSession#startGroupCall`, this class is used to hold information about the call and control it.

## Summary

### Constants
`int` | `REASON_BY_USER_REQUEST` State changed due to a call to `close()` or `MbmsGroupCallSession#startGroupCall`
`int` | `REASON_FREQUENCY_CONFLICT` State changed due to a frequency conflict with another requested call.
`int` | `REASON_LEFT_MBMS_BROADCAST_AREA` State changed due to the device leaving the area where this call is being broadcast.
`int` | `REASON_NONE` Indicates that the middleware does not have a reason to provide for the state change.
`int` | `REASON_NOT_CONNECTED_TO_HOMECARRIER_LTE` State changed due to the device leaving the home carrier's LTE network.
`int` | `REASON_OUT_OF_MEMORY` State changed due to the middleware running out of memory
`int` | `STATE_STALLED` Indicates that the group call is stalled.
`int` | `STATE_STARTED` Indicates that the group call is started.
`int` | `STATE_STOPPED` Indicates that the group call is in a stopped state This can be reported after network action or after calling `close()`.

### Public methods
`void` | `close()` Stop this group call.
`long` | `getTmgi()` Retrieve the TMGI (Temporary Mobile Group Identity) corresponding to this call.
`void` | `updateGroupCall(List<Integer> saiList, List<Integer> frequencyList)` Send an update to the middleware when the SAI (Service Area Identifier) list and frequency information of the group call has * changed.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `java.lang.AutoCloseable`
`abstract void` | `close()` Closes this resource, relinquishing any underlying resources.

## Constants

### REASON_BY_USER_REQUEST

    public static final int REASON_BY_USER_REQUEST

State changed due to a call to `close()` or `MbmsGroupCallSession#startGroupCall`

Constant Value: 1 (0x00000001)

### REASON_FREQUENCY_CONFLICT

    public static final int REASON_FREQUENCY_CONFLICT

State changed due to a frequency conflict with another requested call.

Constant Value: 3 (0x00000003)

### REASON_LEFT_MBMS_BROADCAST_AREA

    public static final int REASON_LEFT_MBMS_BROADCAST_AREA

State changed due to the device leaving the area where this call is being broadcast.

Constant Value: 6 (0x00000006)

### REASON_NONE

    public static final int REASON_NONE

Indicates that the middleware does not have a reason to provide for the state change.

Constant Value: 0 (0x00000000)

### REASON_NOT_CONNECTED_TO_HOMECARRIER_LTE

    public static final int REASON_NOT_CONNECTED_TO_HOMECARRIER_LTE

State changed due to the device leaving the home carrier's LTE network.

Constant Value: 5 (0x00000005)

### REASON_OUT_OF_MEMORY

    public static final int REASON_OUT_OF_MEMORY

State changed due to the middleware running out of memory

Constant Value: 4 (0x00000004)

### STATE_STALLED

    public static final int STATE_STALLED

Indicates that the group call is stalled. This may be due to a network issue or the device being temporarily out of range.

Constant Value: 3 (0x00000003)

### STATE_STARTED

    public static final int STATE_STARTED

Indicates that the group call is started. Data can be transmitted and received in this state.

Constant Value: 2 (0x00000002)

### STATE_STOPPED

    public static final int STATE_STOPPED

Indicates that the group call is in a stopped state This can be reported after network action or after calling `close()`.

Constant Value: 1 (0x00000001)

## Public methods

### close

    public void close ()

Stop this group call. Further operations on this object will fail with an `IllegalStateException`. May throw an `IllegalStateException`

### getTmgi

    public long getTmgi ()

Retrieve the TMGI (Temporary Mobile Group Identity) corresponding to this call.

Returns
`long` |

### updateGroupCall

    public void updateGroupCall (List<Integer> saiList,
                    List<Integer> frequencyList)

Send an update to the middleware when the SAI (Service Area Identifier) list and frequency information of the group call has * changed. Callers must obtain this information from the wireless carrier independently.

Parameters
`saiList` | `List`: New list of SAIs that the call is available on. This value cannot be `null`.
`frequencyList` | `List`: New list of frequencies that the call is available on. This value cannot be `null`.
